STOVE-BACK.

SPECIFICATION forming part of Letters Patent No. 381,713, dated April24, 1888.

Applicati'n filed June 25, 188?. Serial No. 219,594. {No mode.)

T0 on whom it may concern:

Be it known that 1, WILLIAM C. METZNER, a citizen of the United States,residing at Chicago, in the county of Cook and State of lllinois,haveiuvented certain new and useful Improvementsin Stove-Backs; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit apper tains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

My invention relates to that class of stovebacks which are madeadjustable as to length and height, in order that they may he fittedinto stoves having fire-pots of different sizes.

In the accompanying drawings, Figure 1. is a rear view of the mainplate.' Fig. 2 is a r similar view with the end plates in place upon themain plate. Fig. 3 shows the front side of the bottom plates detachedand separated from each other. Fig. 4 is a rear view of the completeback. Fig. 5 is a view of the lower plates joined to each other, butdetached from the other parts and reversed. Fig. 6 is a front view ofthe complete back. Fig. 7 is a view of one end of the lower edge of theback, the front side being turned upward.

The main plate (marked A in the drawings) is composed of the broad fiatpart A, a rearwardlyeurved upper flange, A", and the rearwardly'direetedflange A along the lower edge, and at a short distance from the left endin Fig. l the upper portion of the part A is provided with a bolt-hole,A. At the opposite end there is a similar hole, A

B is the end plate applied at the left in Fig. 2. The main portion of itis shaped to conform to the rear surface of the plate A, and is ofproper width to leave its lower edge lie against the flange A and becovered thereby, while its upper edge is even with therearwardly-directed upper edge of the plate A and covered thereby. Saidflange A should extend rearwardly a distance equal to the thickness ofthe said plate B, so as to make said plate and flange even at the rearof the back. At the height of the hole A the plate B is provided with ahorizontal slot, B, and a bolt, B", passes through said slot and hole Aand binds the plate 13 to the plate A. The lower portion of the plate 13is not bolted to the plate A. but merely rests against the flange A bywhich its corners are prevented from moving 5 downwardly, and the part Aprevents the corners from turning upward; hence, though there is but onebolt used to secure the plate B, said plate cannot rotate upon saidbolt. in other words, there is a channel between the 6 part A and theflange A, into which the plate Bis bound by the bolt B", and the jointbetween the faces of the plates A and B is covered above and below. Avertical strip about an inch wide,(inarked B at the outer end of 6 theplate B, is set back a little to make a depression to receive the edgesof the usual and lining of the fire-pot.

The flange A is broken away alittle at the end of the plate A, and thelower edge of the 7 plate B is extended downwardly past the end of saidflange even with the bottom of the plate A, thus forming a shoulder,13*, to lie against the end of the flange A This limits the movement ofthe plate B inward over the plate A. 7 To make less weight of metal, theinner portion of the plate B may be cut away, as shown in the drawings.

Opposite the plate B a plate, 0, is applied to the other end of theplate A. It is of the 8 same shape as the plate B, excepting that itsparts are transposed from right to left. The horizontal slot is marked0, and the bolt pass ing through said slot and the plate A is marked 0",while the strip which is set back at the 8 outer end is marked C and theshoulder at the lower edge is marked 0.

Fig. 2 of the drawings shows the end plates, B and 0, set in wardlytotheir farthest limit. After releasing the bolts they may each be movedontwardl y adistance equal to the length of the slots. The depressionover the strip B and the similar depression over the strip 0 are alwaysoutside of the ends of the plate A to receive the edges of the endlining, as afore- 9 said.

The parts thus far described may be used as a back when it is desired tohave only horizontal adj ustability.

To afford vertical adjustability, the bottom I plates, 1) and E, areadded to those already described. These bottom plates are narrower thanthe plates A B O, and the main part of the plate E is about as long asthe plate A, while the plate D is only about half that length.

From about the middle of the front face of the plate E to its left endsaid plate is provided with a channel, E, wide and deep enough toreceive the main portion of the plate D. In said channel E a horizontalslot, E is cut through the plate E. Opposite said slot a hole, D,extends through the inner end of the plate D, and a bolt, D", passesthrough said slot and hole and binds said plates together, and the sidesof the channel E prevent the plateD from rotating on the bolt D". Afterloosening said bolt the plate D may be moved horizontally within thechannel E. The outer end of plate D is continued in an upwardly-extendedstrip, D lying behind the strip B and set back to make room for thelatter. Said strip D is provided with a vertical slot, D, and oppositethereto a hole, B extends through the strip B, and a bolt, B passesthrough said slot and hole and binds said plate D to the plate B. Theouter or right end of the plate E is continued in an upwardly-extendedstrip, E lying behind the strip 0 Said strip is provided with a verticalslot, E", and opposite thereto a hole, 0*, extends through the strip 0and a bolt, 0 extends through the said slot and hole and binds saidplates E and 0 together. After loosening the bolts 0 and B said plates Dand E may be raised or lowered with reference to the other plates, thusincreasing or decreasing the height of the back. To lengthen the backwhen all the plates are used, the bolts B, B", and C1 are to beloosened. The plates D and E are further held against rotation on thebolt 0 by the binding produced by the meeting of the webs F, which unitethe strips 13, C D and E to their respective plates.

I claim as my invention- The combination, with the main plate having therearwardly-curved upper edge and the rearwardly-directed flange at itslower edge, of slotted end plates lying between said rearwardly-curvedupper edge and said flange, and each secured to said main plate byabolt, and two overlapping bottom plates, one of which is channeled toreceive the other, (the sides of 0 the channel of the former engagingthe edges of the latter,) and which are bound together adjustably bymeans of a bolt passing through a slot and hole in said plates, and eachhaving a vertical slot at its outer end through which a bolt passes andsecures it to the adjacent end plate, substantially as shown anddescribed.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM G. METZNER.
